DS1254YB-100 Overview
In the 168-BGA package, real time clocks is embedded as a dependency.Tray is the package format.In this electrical RTC, the supply voltage is 4.5V~5.5V.Phantom Time Chip is the type of electrical real time clock that is being used.As you can see from the diagram, this electronic component is mounted in the way of Surface Mount.There should be 0°C~70°C operating temperature.When operating, electronic time clocks are possible to ensure that Leap Year, NVSRAM are maintained.The family in which RTCs belongs are DS1254.A voltage of 3V is supplied to this electrical digital time clock.RTC times embed a memory of 2MB for storing programs and data.Mounting type Surface Mount is chosen for the RTC module.There are 168 pins on it.Optimal efficiency can be achieved by maintaining the supply voltage at 5V.Frequency 100GHz is achievable.
